Flight controls Flashcards
The aileron controls the aircraft movement about the ?
Roll or longitudinal axis.
The elevator controls the aircraft movement about the ?
Pitch or lateral axis.
The rudder controls the aircraft movement about the
The vertical axis
Roll Control provided by?
Ailerons. Increase the lift on one wing while decreasing lift on opposite wing
Pitch Control provided by?
Elevator up will cause nose of aircraft to go up
Yaw Control provided by?
Rudder is deflected to the right the aircraft will turn right.
What is stabilator?
The entire horizontal stabilizer can be moved as one unit to pitch the aircraft nose up or down.
What happen when the trim tap is deflected upward?
air over the elevator is deflected upward and the elevator moves downward, creating a nose down trim condition.
3 types of trim taps?
- Aileron
- Elevator
- Rudder
Secondary job of the trim tap is?
-Servo( help with some work for the pilot) opposite
direction as flight control
-Antiservo (works against the pilot) same direction as a
flight control
Balance tap is a ?
Servo panel that is not a trim(Aileron balance panels and tab decrease the amount of force necessary to move the aileron in flight)
Devices for Controlling Lift
- Flaps
- Slats
- Slots
- Spoilers
- Brakes
Primary Phases of flight
- Climb, including take off
- Cruise, Level of Fight
- Descent, Including landing
What is a Slot ?
-A slot is a device which allows air from below the wing
to flow to the upper surface of the wing.
-This energizes the boundary layer at high angles of attack.
Function of Slat?
A slat moves out of the leading edge of the wing at high angles of attack to form a duct for high energy air. and also help for lifting.
Types of Spoilers
- Ground Spoilers
- Flight spoilers
Flight spoilers are used in flight to?
Reduce lift, create drag and control the aircraft.
Ground spoilers are used ?
on the ground after landing and during high speed taxi to destroy the lift on the wing and increase down-force and drag
Speed Brakes are devices used to?
- To slow the aircraft down in flight or on landing.
- They are deployable surfaces that are hydraulically or mechanically moved into the slipstream to create drag.
Other control surfaces?
- Stabilator
- Trim Tabs
- Balance Tabs
